Comparative Results between Loudspeaker Measurements Using a Tetrahedral Enclosure and Other Methods

Authors: Hill, Geoff

AES Convention 136 · Paper 143 · April 2014

Abstract

A major problem for the loudspeaker and transducer industries throughout the world, is an inability to rely upon measurements routinely exchanged between suppliers and customers. This paper updates "Consistently Stable Loudspeaker Measurements Using a Tetrahedral Enclosure" - EB4-7 published in 2013, with comparative measurements using results by other people, equipment and methods: Small IEC Baffle in Anechoic Chamber and Large IEC Baffle Outside vs a TTC 350. These Test Chambers give us the capability to approach "Design Quality" measurements easily throughout the entire supply chain, reducing errors and improving quality whilst driving down the cost of measurement.
